1. A plant has the following characteristics: Beginning with two true breed individuals (one mutant, one wild type) answer the following questions. Assume all alleles behave according to Mendel’s principles.
A. List all possible genotypes that could produce a plant with short pollen and tall plants.
B. How many F1 generation plants do you predict to be short pollen and tall plant? Explain your answer.
C. What possible genotypes could produce an individual with phenotype long pollen and tall plant? Describe an experiment to determine the correct genotype of this individual.
| ALLELE | TRAIT |
| A | Long Pollen Grain |
| a | Short Pollen Grain |
| B | Tall plant |
| b | Short plant |
Solution
A. List all possible genotypes that could produce a plant with short pollen and tall plants.
Answer:
Short pollen and tall plants = aaBb, aaBB,
B. How many F1 generation plants do you predict to be short pollen and tall plant? Explain your answer.
P1 = Long Pollen Grain, Tall plant (AABB) x Short Pollen Grain, short plant (aabb)
F1 = 0
C. What possible genotypes could produce an individual with phenotype long pollen and tall plant? Describe an experiment to determine the correct genotype of this individual.
long pollen and tall plant = AABB, AaBB, AaBb
